CURT 57251 7-Way RV Blade to 5-Way Flat Trailer Wiring Adapter | No-Splice, Durable

Overview

When towing, mismatched plugs can complicate power delivery from a tow vehicle to a trailer. The CURT 57251 adapter bridges a 7-way RV blade vehicle socket to a standard 5-way flat trailer plug, enabling reliable lighting and accessory connections without extra wiring.

Built for real-world use, this adapter emphasizes ease of use and durability. It plugs directly into your vehicle and trailer without splicing, and the rugged black plastic housing resists rust in damp conditions, helping you tow with confidence across a wide range of trips.
